All entries must be of an architectural nature, and must be authored by one individual. Entries can be elevations, sections, or perspectives, and can be conceptual or final renderings. Exploration and innovation in unique techniques are encouraged. While there is no limit to the number of entries one can submit, submissions awarded in past Ken Roberts competitions are not eligible. Sketchbooks as a whole will not be accepted; a single, clearly marked page within the sketchbook may be entered.
